' The numeral 10 indicates the preferred' vform ofV valve casing. Casing 10 is ar- Be it 'known that I, OSCAR L. Simoncini,

a-citizenof the United States, residingat Jamestown, county of Chautauqua, and State of New York, have invented-new and useful AImprovements in Valves, of which the following-taken in connection with the accompanying drawings, is a' full, clear, and exact description..-

The invention relates to double acting valves; and the object of the improvement is to provide two connected valves with means for operating the valves which shall cause said valves to seat correctl upon the valve seats in the control of hi pressures of gas and other fluids; `and t e invention consists in the construction and arrangement of the parts as described in this speciication and shown in the accompanying drawings.

In the drawings, Figure 1 is a sectional view of the preferred form of the valve. Fig. 2 is a bottom plan view as shown in Fig. 1. Fig. 3 is a sectional view at line X X in Fig. 1.l Fig. 4 is a top plan View of the valve, as shown in Fig. 1. Fig. 5 is a lengthwise sectional view of a modification of the valve as adapted to use on a continuous pipe or gas main.

Similar numerals refer to corresponding ranged with the two chambers 11 and 12.

For certain uses the chamber 11 is preferably left open ended.- Between chambers 11 and 12a partition 13 is provided having the i valve seats 14- and 14 on the opposite sides and the opening 15 therethrough.-`

[At'the ower end a bushing or hollow nut 16 is provided into which the pipe 17 is connected. Across the upper end ofbushi line with hole 19.

in 16 a guide bar 18 is provided having a ho e 19 therein exactly in the center of the opening in the nut 16. Across the upper videdl with a hole 21 in the center of the opening within the casingso astobe in A valve stem 22 is slidably in the holes 19 and 21 and bears thereon infathreaded central portion the two Valves 23 and 24, which valves are held in place by suitable nuts on each side of the valve plates. Valves 23 and 211 have packing25 and 25 respectively, `preferably `of leather, so as to set tightly onl the valve seats 14 and 14 respectively, andthereby insure the closing of the opening 15 Whichever way the valve stem 22 may be moved.

A lever or operating handle 26 is pivotally attached at 27 to the exposed end of valve stem 22. The' upper edge of the casing 10 is extended up in the lugs 23v and a link 29 is pivotally attached by means of a pin 30 through lugs 28 andby a pin 31 to handle 26 so that lin-k 29 'Worksback and forth as the lever or handle 2 6 is reciprocally moved without moving the valve stern ,22 out of line. It is apparent that hy this arrangement the valve stemv will be held'. perfectly in line so. that one or the other of 1 the valves 23 and 24 will lit perfectly upon its seat in whichever direction the handle 26 is moved.v

In Fig. 5 a modified form of the valve is shown withl a closed casing 32. Casing 32 has the two chambers 33 and 34C, corresponding tov chambers 11 and 12, having outlets 36 and 37 tothe main pipeline 35. The casing 32 is turned aside from the main line lof the pipe and enlarged sufficiently to permit of the insertion of the valves 23 and 211 and to provide the two chambers therefor and the valve seats 14.- and 14 between the chambers. A valve stem 22 is mounted therein through a guide p1ug'38 at the handle actuated end of the valve stem. A suitable stuiiing box may be provided in plug 33 to revent the escape of the fluid. Lever 26 is attached at 27 to the valve stem 22 and link 29 is pivotally attached to suitable lugs 39 on the edg'eof the casingl 32. At the opposite end ofthe valve stem, instead of the ushing 16, a plug 40 is provided having a recess 11.ther5ein to receive the end of the valve stem 22, a guide bar 18 with central hole 19 being provided across the opening 41 in plug 10 the same as on bushing 16.

The open-ended valve casing 10 is specially applicable for use within the tank ci the gas regulator, shown in Letters Patent Number 973,396. It is apparent that the open end allows thegas free opportunity of escape upon all sides within the regulator tank. A coil spring 42 is referably placed around shaft 22 between t e lower nut for par valve 25 and guide bar 18. The strength of 'spring 42 may beso adjusted to the pressure asto automatically close theivalve, when notlisaid valve stem with suite 15- actuated by lever 26. It is obvious, however,

that the valve may be operated by means of partition in said casing having an opening therethrough, valve seats on the opposite sides of said partition around said opening, guide bars at the opposite ends of said casing having holes therethrough in line with the center of the opening in said partition, a valve stem slidably mounted through said holes in said bars, valve plates mounted on le packing adapted to fit the respective valve seats', a link pivotally mounted on said casing, and an f operating lever pivotally attached to said link and valve stem, substantially as and for the purpose specified.

2. A valve comprising a casing,

therethrough, valve seats on the opposite a central j partition in said casing having an opening Loaaeva a hollow bushing in one endl of said casing, i

a bar across the inner end of said bushin having a hole therethrough, the opposite en of said casing left open, a bar across said open endof said casing having a hole therethrough, a valve steml slidably mounted through the holes in said bars, valve lates mounted on said valve stem with suitable packing adapted to fit the respective valve seats when said [stem is moved endwise, a

link pivotally mounted on'the open end of said casing and an o erating leverpivotally attached to said lin and one end of said valve stem, substantially as and for the purpose specified. t

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
